at the end of the day, people want to long AND short with capital efficiency. right now there are only two types of venues that allow this for a regular user:
a perp D(C)EX, and an Aave style two-way lending pool
this makes Aave the closest we get in terms of a defi prime brokerage (until we launch Mobius)
"problem" with this model is, there are much fewer spot assets that are safe to short than long, because of constrained liquidity.
that's why you can't short (borrow) CRV/LDO/1INCH etc. on Aave
but interestingly, you can freely short them on a perp DEX, because the house don't lose money in a squeeze (the traders do), unlike Aave, who has to cover bad debt
@MobiusExchange is combining both: you can use tokenized stocks/RWA/defi positions as collateral (long), to short perp. on top of that, you also can leverage up by borrowing against your portfolio
